JCH AI Bridge Beta
Remote-control your local AI agent from Just Connect Here
The JCH Bridge is a small app that lives in your menu bar. It automatically connects an AI companion account (@yourname_ai) to an AI agent of your choice — for example Claude Code, the Anthropic or OpenAI API, or a local LLM instance via Ollama. You send a message to the companion in Messenger, the agent on your machine executes it, and the response comes back in the chat.
You sign in once with your normal JCH account — the @yourname_ai account is then created automatically. If your main account is deleted or deactivated, the AI account disappears with it automatically.
⚠️ Important: Your responsibility, your cost
The bridge forwards your messages to an agent you run yourself. What that agent does on your computer — read files, run commands, access the internet — is determined entirely by your configuration. The provider (see legal notice) accepts no liability for actions performed by your agent on your behalf, and provides no support for the agent itself.

Most agents require their own subscription or API key. The bridge does not manage API keys and routes nothing through JCH servers. Examples:
- Claude Code / Anthropic API: Anthropic subscription or pay-as-you-go
- OpenAI / ChatGPT API: OpenAI account with API access (a ChatGPT subscription does not count)
- Google Gemini: free tier via aistudio.google.com — just a Google account, no billing
- Ollama / LM Studio: free, runs entirely on your machine — requires enough RAM/GPU
The bridge itself is free. A JCH account is required.
Download
Setup
- Install the .dmg: double-click the downloaded
JCH-AI-Bridge.dmg, then drag the app into your Applications folder.
- Launch the app: the AI Bridge appears as an icon in your menu bar. On first launch the settings window opens.
- Sign in: with your normal JCH account (username + password, 2FA if enabled). The
@yourname_ai account is created automatically — no token to copy.
- Choose an AI service: Claude Code (CLI), Anthropic/OpenAI API, or Ollama. Enter the API key, working directory or Ollama URL depending on your choice.
- Start the bridge: click Start. The icon shows the status; you can close the window — the app keeps running in the menu bar.
- Try it in Messenger: start a new chat with your
@yourname_ai contact and send a test message.
Known limitations
- Home machine must be running: if the bridge is offline, no one answers. You'll get a response after restart at the latest, but no live feedback “agent offline”.
- No live mirror in VS Code: for Claude Code (CLI) the bridge starts the agent as a separate process. With the “continue last session” option it continues the most recent session in the chosen directory — but the chat panel in your active VS Code session does not see the bridge's messages.
- One request per room: while the agent is working, additional messages in the same room are answered with a warning. Complex requests take time — responses may take minutes.
Security notes
- End-to-end encrypted: the chat with your
@yourname_ai contact is E2E-encrypted like every other JCH chat. Your AI commands do not travel through the server in plain text.
- Your credentials are used only once to sign in. Only the AI companion account's token is stored — in the macOS Keychain, never in plain text.
- Enable 2FA on your JCH account. Anyone who takes over your account can also remote-control your agent.
- The bridge checks the sender of each message: only messages from your own account are executed, everything else is ignored. Invites from strangers are automatically declined.
- For Claude Code, think carefully about which working directory you give the agent. The agent inherits your user's permissions — an overly broad directory means a poorly worded request can cause significant damage.
Support & questions
For questions about the bridge or bug reports: mail@jch-technologies.de.
For questions about the specific agent (Claude Code, OpenHands, Ollama…) please contact its provider — we have no insight into their internal configuration.
